Using salinity to predict rainfall
Earth ScienceAsked by: Cindy Rogers How does rainfall affect salinity? Where more rain or snow falls over the ocean, it dilutes the salts in the seawater there. As a result, the water becomes fresher with time. If seawater becomes saltier, it may mean that rates of evaporation have increased or that precipitation has decreased over time.
Other than tectonic activity, what can reshape a world’s surface?
Natural EnvironmentsBeyond Plate Tectonics: How Worlds Get a Makeover (Without the Shoving) Okay, so we all know tectonic plates are a big deal when it comes to shaping a planet. Earthquakes, mountains, the whole shebang. But let’s be real, there’s way more to planetary makeovers than just continental shoving matches. Think of it like this: tectonics
Could glacial melt alter plate tectonic movement?
Earth ScienceAsked by: Katelyn Roy Are glaciers related to plate tectonics? According to new research, the transition to plate tectonics started with the help of lubricating sediments, scraped by glaciers from the slopes of Earth’s first continents. Can melting glaciers cause earthquakes? Scientists have known for decades that melting glaciers have caused earthquakes in otherwise tectonically
What sort of a plate is the Sunda plate?
Geology & LandformThe Sunda Plate: Southeast Asia’s Shaky Foundation Ever wonder why Southeast Asia seems to be constantly making headlines for earthquakes and volcanic eruptions? A big part of the answer lies beneath our feet – or rather, beneath the ocean and islands of the region – in the form of the Sunda Plate. This isn’t one
Where can I find a data set containing wetland loss by decade
Earth ScienceAsked by: Jim Greenwood What percentage of all wetlands has been lost? It has been frequently stated, but without provision of supporting evidence, that the world has lost 50% of its wetlands (or 50% since 1900 AD). How much wetland has been lost in the US? It is esti- mated that, on average, over 60
Do ice crystals form in running super-cold water?
Earth ScienceAsked by: Ellen Belanger At what temperature do ice crystals form? Fig. 1. At temperatures above 0°C, water remains a liquid. Between 0 and about -36°C, water only crystallises into ice if coerced e.g. by making freezing more likely by there being an ice nucleus, such as a dust particle, present in the water. How
